FILE-FABRIC LOOM.

To all whom it may concern:

Be it known that I, HERBERT J. HOPE, a citizen of the United States,residing at Sanford, county of York, State of Maine, have invented anImprovement in Pile-Fabric Looms, of which the followingdescription, inconnection with the accompanying 'drawing, is, a specification, likecharacters on the drawing representing like parts.

This invention relates to pile fabric looms of the type in which thepile is formed over a pile wire. In pile fabric loo-ms of this type, theshuttle box onthe side of the loom upon which the wire motion is locatedis frer quently sustained on a movablesupport which is actuated bysuitable devices to'move it relative to the lay asthe latter vibrates,the purpose of this construction being to cause the shuttle box to bemoved rearwardlyrelative to the lay when the latter beats up so that theshuttle box will beat up out of the way of the wire motion. The presentinvention relates to means for thus moving the hereinafter.

- now be described, after which the novel fea- I In order to give anunderstanding of-my invention, I have illustrated in the drawing aselected embodiment thereof which will tures will be pointed out in theappended claim. I

Figure 1 is a loom frame showinga portion of the lay and theshuttle boxand also, illustrating my improved shuttle box-controlling "mechanism,said figure showing the lay in its rearward position with theshuttle-box in proper position to have; the shuttle picked through theshed; I 7 Fig.9 is a similar view showing the relative position of theparts when the lay is in its forward position]. In Figs. 1 and 2 the 7frame for supportng the rock-shaft of the shuttle-box-controllingmechanism is omitted- F ig. 3 is a plan view.

sufficient portion of a loom to permit my iavention to be understood.

1 indicates a portion of the loom frame in which is journaled the crankshaft 2 from which the lay- 3 is operated, said lay being connected tothe crank shaft by theusual connecting rods 4. The lay is sustained onthe usual lay-swords 5 which are mounted on the rock-shaft 6 journaledin the'loom frame. The lay 3 carries the usual reed which, however, hasbeen omitted frointhe drawings in orderto simplify the illustration.Neither have I attempted to show the com plete wire motion as this maybe of any usual construction, but I have simplyillustrated at 8 aportion of the wire-bar or guide in which the pile wires are guided asthey are inserted into or removed from the fabric, said wire-bar beingsustained on the portion 9 of the frame.

7 indicates the shuttle box which is on that side of the loom upon whichthe wire motion is located, said shuttle box being mounted forfore-and-aft movement relative to the layas usual in pile fabric loomsof thistype, so that when the lay is at the rearwardend of its stroke,the shuttle box may be properly positioned to have the shuttle pickedthrough the shed, while when the lay is atthe forward end of its stroke,the shuttle rbox'may be moved rearwardly relative to the lay so that itwill not interfere with the wire motion. j

I have provided herein a simple mechanism for thus controlling theposition of the shuttle box 7 relative to the lay by which the shuttlebox is positively held in its proper position at all times. The shuttlebox 7 is shown as supported on an arm or support 10 which is pivotallymounted on the rocker 6, said support 10 being capable of swingingmovement about the rocker, thus to move the shuttle backward and forwardrelative to the lay 3. The lay is herein shown as having secured theretoa guiding member 11.

having a guiding slot 12 therein in which operate the ends of guidingpins 13 carried by. the shuttle box. I

The lay 3 has one end of a link or connection 15 pivotally securedthereto at 14, the other end of said link being pivotally connected at16 to an arm 17 fast on a rock-shaft 18 that is journaled in suitablebearings 19 sustained by the portion 9 of the loom frame.

The rock-shaft 18 thus receives an oscillatory or rocking movement fromthe backrock-shaft 18 and the shuttle-box whereby such oscillatorymovement of the rock-shaft will cause the shuttle box to have a'movement relative to the lay thereby to place saidbox in proper position forthe shuttle to be picked through the shed when the lay is in itsrearward position and to move the shuttle box out of the way of the wiremotion when the lay is in its forward position. The connections hereinshown for this purpose comprise two arms 20 fast'on the rock-shaft 18and which are connected to the support 10 by means of two links orconnecting members'21. The arms 20 are shorter than the arms 17, and asa result, the fore-and-aft movement of the connections 21 willbe less inamplitude than that of the link or connection 15. i

Fig. 1 shows the lay in its rearward position (which is the position itoccupies when the shed is open) and the shuttle box in proper positionto have the shuttle picked through the shed. As the lay moves forwardintothe position shown in Fig. 2, the connection 15 will swing the arm17 for? wardly, thus turning the rock-shaft 18 clockwise, Figs. 1 and 2.This movement of the rock-shaft will operate through the arms 20 andthelinks or connections 21 to move the supports 10 and the shuttle box 7forwardly, but owing to the fact that the arms 20 are shorter than thearm 17, the connections 21 will be moved at a slower speed than theconnection 15 and will move through a lesser distance than saidconnection 15. During this forward movement of the lay, therefore, theshuttle box is mov-v ing at a slower rate of speed than the lay so thatwhen the lay reaches its forward position shown in Fig. 2, the shuttlebox will only have traveled a portionof the distance that the lay hastraveled and will be.

located in the relative position shown in F i-g. 2, in which position itis out of the way of the wire motion. When the lay is moved rearwardlyagain, the shuttle box will also be moved rearwardly, but at a slowerspeed, and at the end of the rearward stroke, the shuttle box will bepositively positioned in the position shown in Fig. 1 which is thecorrect position to have the shuttle picked through the shed. Theshuttle box thus derives its motion from the lay through positiveconnections which invariably maintain the shuttle box in the a properposition 'at all times. There is, there fiopiesof'this patent may beobtained for fore, no possibility of the shuttle box becoming misplacedrelative to the lay.

'Since the sliilttle box-controlling mechanism positive in its operationand does not depend upon cams or springs, it is possible to operate theloom at an increased rate of speedwithout danger of the shuttle-boxbecoming displaced The device is, therefore, especially adapted for.high speed operation.

I have shown herein adjustable connec tions between the link 15 and thearm 17 and also between the links 21 and the arms 20 so that the entireoperating mechanism will be kept tight and free from back-lash orloose-play. r

The-arm-17 is shown as having a block 22 pivotally connected thereto at16, said block having an aperture through which the end of theconnection 15 extends. The. connection 15 is provided with two clampingnuts 23 by whichthe block 22 is firmly secured to the connection,saidblock thus constituting the means for pivotally connecting the linkor connection 15 to the arm 17. Similarly,

the rear end of each of the connections 21 extends through a block 241:which is pivoted to one of the arms ZO a-t 25, and each connection -21is provided with two clamping nuts 26 which adjustably secure the block2 1 to said connection. This construction not only provides for takingupall loose play and maintaining a tight connectionbetween the lay andthesupports 10, but also pro rides for adjusting thearms 17 and 20relative to each other if such adjustment is-necessary for the purposeof properly-positioning the shuttle box at anyipoint in the cycle ofoperations. The armsll' and; 20 are preferably adjustably secured 'totherock-shaft 18 so that they can be adjustedangularly thereabout,-saidarms being maintained in the desired adjusted position by means ofset-screws 27.
